SLEIGH-RUNNER ATTAOHMEN FOR VEHICLES.

Specification of Letters Patent.

Patented Oct. 13, 1908.

Application filed April 27, 1908. Serial No. 429,413.

To all whom it may concern:

Be it known that I, FRANCIS KORFF, a citizen of the United States,residing at Lansing, in the county of Ingharn and State of Michigan,have invented a new and useful Sleigh- Runner Attachment for Vehicles,of which the following is a specification.

This invention relates to sleigh runner attachments for wheeledvehicles, with especial reference to sleigh runner attachments for babycarriages.

The object of the invention is to provide an improved form of suchattachment which may readily be applied to any existing vehicles of thecharacter described and which may be easily operated to change thevehicle from a wheeled carriage to a carriage adapted to be moved abouton sleigh runners.

The invention comprises a pair of sleigh runners attached to the axle ofa wheeled vehicle and mechanism whereby the runners may be placed inoperative position or displaced therefrom.

The invention further consists in certain novel details of arrangementand combinations of parts, hereinafter fully described, illustrated inthe accompanying drawings, and specifically claimed.

In the accompanying drawings, the figure represents a perspective viewof the attachment as applied to the axles of a vehicle.

The vehicle axles are indicated by the numeral 10. Upon the axles 10 aredetachably In the present illustration the bearings 11 are supposed tobe mounted upon the front axle, while the bearings 12 are mounted uponthe rear axle. In the bearings 11 of the front axle is mounted a U-frame13 which is provided with suitable braces, as indicated at 14. The U-frame 13 is so mounted in the'bearings 11 that the legs of the U extenddownward, as illustrated in the figure, these legs being substantiallyvertical when the sleigh runners are in operative position. In thebearings 12 is a similar U-frame 15 provided with a brace iron 16.Located medially of the frame 15, the brace iron 16 has a downwardlybent portion, as indicated at 17. The U- frames 13 and 15 have the lowerends of their legs flattened, as indicated at 18, and pivotallyconnected thereto are runners 19.

In the preferred form of the invention, the runners 19 are made of angleiron with up wardly bent forward ends, as clearly in cated in thefigure. Pivotally attached to the runners 19 and passing between the U-frame 15 and the downwardly bent portion 17 of the brace iron 16 is aY-bar 20 rovided with a notch 21 adapted to engage tl ie downwardly bentportion 17 before referred to, and further provided with a stop 22 toprevent said Y-bar being displaced from position relatively to thedownwardly bent portion 17 and the U-frame 15. Attached to the runners19 and the U -frame 15 are springs 23 which normally tend to place theparts in the position shown in the dotted ines in the figure.

In the operation of the device, let it be assumed that the parts are inthe positions indicated by the full lines. The sleigh runners will thenbe upon the ground and the device can be used as a sleigh. Should it bedesired to use the vehicle'as a wheeled vehicle, it is merely necessaryto raise the Y-bar 20 sufficiently to disengage the slot 21 from theportion 17 of the brace iron 16. The springs 23 will then pull thesleigh runners into the position shown by dotted lines. Should it beagain desired to convert the vehicle to a sleigh, it is merely necessaryto push down upon the Y-bar 20 until the slot 21 again engages theportion 17 of the brace iron, and the vehicle will thus be convertedinto a sleigh. There is thus provided a simple and efficient means tochange a wheeled vehicle to a sleigh, and vice verse.

I claim 1. In a device of the kind described, a pair of wheeled axles,U-frames carried on said axles, a brace bar on one of said U-framesprovided with a downwardly extending median portion, and a bar passingbetween the downwardly extending portion and the U- frame attached tosaid axles and provided with a slot therein adapted to engage thedownwardly extending portion of the brace bar and hold said U-frame infixed relation to said axles.

2. In a device of the kind described, a pair of wheeled axles, U-framescarried on said axles, sleigh runners pivotally mounted on saidU-frames, a brace bar on one of said U- frames provided with adownwardly extend- 1 In testimony that I claim the foregoing us ingmedian portion, a Y-bar provided with a i my own, I have hereto affixedmy signature notch therein held between said downwardly extendingportion 01" the brace bar and said U-irame and pivotally connected tosaid sleigh runners, and springs normally raising said runners from theground.
